PORK-FAT-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 328,667, dated October 20, 1885.

Application filed April 9, 1885. Serial No. 161,725.

To all whom it may concern:

Be it known that I, BERNARD GLOEKLER, of Pittsburg,in the county of Allegheny and State of Pennsylvania, have invented certain Improvements in Pork-Fat Cutting Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification Figure 1 being a top view of a pork-fat-cutting machine provided with my improvements; Fig. 2, an end view of the same; Fig. 3, a partial view of the other end of the machine; Fig. 4, a front view of a vertically sliding or reciprocating knife-head or set of knives used on the machine and constructed with my improvements; Fig. 5, a vertical cross-section of the same in a planeindicated by the line a: m, Fig. 4; Figs. 6 and 7, respectively, side and edge views of one of the knives of the cutter-heads.

Like letters designate corresponding parts in all of the figures.

My improvements are applied to a kind of cutting-machines in which the fat or other material is placed in quantity in a strong close receptacle and forced out at one end thereof by" a piston, and in passing out of the receptacle is forced between two sets of knives reciprocating endwise, one in a vertical direction and the other in a horizontal direction, to cut the material into narrow strips, and these strips are cut off into short pieces or blocks by one or more revolving knives moving in a circle just outside of the outer set of reciprocating knives.

My improvements relate, first, to the construction of the vertically and horizontally reciprocating knife-heads, whereby the separate knives or blades are removed and replaced with great facility for sharpening, cleaning, replacing when broken or injured, or for any other purpose, and whereby the distance between the several knives or blades in each knife-headway be changed at will, and that easily and quickly, for cutting the fat into larger or smaller strips, as desired, and, second, in the means of changing the frequency of the cutting effected by the revolving knives, whereby the strips cut by the reciprocating knives are cut off into smaller or larger blocks at will.

(N0 model.)

The principal parts of the machine, as represented in the accompanying drawings, to which myimprovements are applied are the following: A represents the frame of the machine; B, the receptacle, having its upper side, a, hinged so as to be raised, as shown in Fig. 1, for readily putting the fat or other material into the receptacle; 0, the piston by which the fat is forced out of the receptacle; D, a rack projecting from the rear side of the piston, and gearing into a pinion on the shaft of a worm-wheel, E; G, the worm -shaft with a crank-wheel H thereon for slowly turning the worm-wheel and forcing the piston forward with great power; I, a crank-handle for turning the worm-wheel backward and thereby quickly drawing back the piston in the receptacle, the worm-shaft being then ungeared from the worm-wheel by moving it endwise till the worm is out of gear therewith; J, the vertically-reciprocating knife-head, next to the outlet end of the receptacle; K, the horizontally-reciprocating knife-head,locatedj ust outside of the other knife-head; L L, the revolving knives for cutting off the strips of fat made by the reciprocating knives, which receive their reciprocating movement by means of a double-armed vibrating lever, M, turning on a fixed pivot, b, the ends of the arms thereof having short slots 0 d, which receive pivot-pins, respectively, on the knife-heads J K, and the lever itself being moved by a connecting-rod,

N, connecting it with a crank, c, on the shaft- O, on which the revolving knives L L are mounted. Theshaft O is turned by the worm shaft G, geared thereto by a bevel-wheel, P, on the said worm-shaft, and another bevelwheel, Q, on the said shaft 0, the two bevelwheels being ungeared for allowing the wormshaft to be moved endwise to disconnect it from the worm wheel and to stop the motion of the knives when the piston is to be drawn back to renew the charge of fat in the receptacle by having the bevel-wheel Q slide sufficiently on its shaft 0, as indicated by dotted lines in Fig. 1. A shifting-lever, R, is employed tomove the bevel-wheel Q, which is held in gear by a hinged latch, f, dropping in back of the wheel-hub, as shown, and to be lifted out of the way when the bevel-wheel is to be ungeared from the bevel-wheel P.

Now, as to my improvements in the con- I shown in Figs. 6 and 7, has a rivet or pin,

through it, near one end, projecting a little from the opposite sides thereof, and in the other end of each knife is a hole, h. The pin 9 in each knife fits into an oblique or hooking cross slot or notch in a movable cross'bar, J, of the knife-head, near one end thereof, being socketed in the said cross-bar,so as to retain its place there securely and in an accurate position. A wire or rod, U, passes into a hole lengthwise in the cross-bar T, and through the holes in the ends of the knives therein,whereby the knives are all secured to the cross-head. A screw, 13, extends outward from the movable or sliding cross-bar J, through a hole in a fixed end piece, k, of the knife-head, and a nut, Z, is screwed upon the screw t outside of the said end piece. On screwing the nut tightly against the end piece, k, of the head the cross-bar J is drawntoward it, and all the knives are drawn taut and secured firmly in the head, and by turning the nut back a little all the knives are loosened in their slots, when on withdrawing the rod U any one or all or any number of the knives may be easily removed from the knife-head, the slots being open on one side of the head for allowing the knives to be inserted and withdrawn laterally therein.

Aslight modification of the means of securing the knives in the knife-head is shown in the drawings in the construction of the horizontal knife-head K, as shown in Fig. 2. Here the pin which works in the slot d of the vibrating lever M is not on the knife-head proper, as is the pin 0 on the vertical cross-head, but on the cross bar T; but the effect is the same.

This ready removability of the knives in the knife-heads is of great value and importance for the purpose of sharpening the knives as often as desirable and of replacing broken or injured knives at any time, requiring no skill nor special instrument'for the purpose. It is also of much value and importance to enable the attendant or owner to remove the knives for cleaning and oiling, which is necessary to preserve them in good condition when the machine is out of use forfany considerable length of time, to prevent the rusting of the knives, which would injure them and render the machine hard to operate. Moreover, this capability of the machineenables me with one set of knife-heads and knives only to vary the distance between the knives at will and by a few minutes adjustment, so as to desired. Thus the knives, when all are in place in the knife-heads, will cut the fat into the narrowest strips of which the machine is capable-say one fourth of an inch in thickness-the distance between the knives. Then by removing one half of the number of knivesevery alternate knifethe knife-heads are at once adapted to cut the fat into strips twice as thick as before-say half an inch. Again, by removing two-thirds of the knives, or leaving one, removing two, then leaving one again, then removing two again, and so on, the strips will be three-fourths of an inch thick on the assumed distance of the knives; and by removing three-fourths of the knives in a similar way the strips will be one inch thick. Both sets of knives are adjusted similarly, or generally so, and they cut the strips to equal thickness both ways.

Then for adjusting the revolving knives so as to cut off the strips of fat into blocks varying in length to correspond with the different thicknesses cut, or otherwise, my improve ment is as follows: The bevel-wheel Q on the knife-shaft O has two or more sets of gearteeth, a 0, (two sets being shown in Fig. 3,) one set being concentric with and within the other; and the bevel-wheel P on the wormshaft G is adjustable upon the shaft by means of aset-screw, 1), so that it may be brought into gear with either set of gear-teeth on the bevel-wheel Q, as indicated by full and dotted lines in Fig. 3. When this bevel-wheel P is in gear with the inner set of teeth, a, the shaft 0 will be rotated, say, twice as fast as when it is geared with the outer set of teeth,0. Besides one of the knives L L is removably attached to the other by bolts q q, or their equivalent, so that either one or both knives may be used at will, and it is obvious that the two knives will out twice as often as one will, the speed of the shaft 0 remaining the same. The parts of the machine are so proportioned and adjusted that when the bevel-wheel P is in gear with the inner set of teeth, a, on the bevel-wheel Q, and both knives L L are on the shaft 0, the shortest blocks or pieces of fat will be out, say, one-fourth of an inch long. Then by shifting the bevel-wheel P so as to gear into the outer set of teeth, 0, on the bevelwheel Q, the two knives L L remaining on the shaft, the knives will out only half as often as before, making blocks,say,one-half inch long. Finally, the bevel-wheel P remaining in gear with the gear-teeth 0 on the bevel-wheel Q, by

removing one of the knives L L, the said rehavingabeve1-wheel,P,adjustab1eonthe shaft from, substantially as and for the purpose lengthwise therepf, a knife-shaft, 0, provided herein specified. with a bevel-wheel, Q, movable upon the shaft lengthwise thereof, and having two sets of 5 gear-teeth for gearing into the teeth of the Witnesses:

bevel-wheel P, and two knives, L L, on the 4 JAMES F. MOKEAN, knife shaft,0ne being readily removable there- 1 J OS. VOGEL.
